(Phys.org)—A team of researchers with members from several institutions in Japan has developed a new way to edit genes that involves cutting just one strand of DNA rather than both of them, as is normal for CRISPR-Cas9. ...

Researchers at the RIKEN Evolutionary Morphology laboratory and other institutions in Japan have shown that complex divisions in the vertebrate brain first appeared before the evolution of jaws, more than 500 million years ...

A new study aimed at understanding habitat needs for Pacific lamprey in western Oregon found this once-abundant fish that is both ecologically and culturally significant prefers side channels and other lower water velocity ...

Lamprey—slimy, eel-like parasitic fish with tooth-riddled, jawless sucking mouths—are rather disgusting to look at, but thanks to their important position on the vertebrate family tree, they can offer important insights ...

If you never understood what "ontogeny recapitulates phylogeny" meant in high school, don't worry: biologists no longer think that an animal's "ontogeny", that is, its embryonic development, replays its entire evolutionary ...

Bile salts scream seduction – for sea lampreys, that is. New research at Michigan State University shows that bile salts, secreted from the liver and traditionally associated with digestive functions, are being used as ...

Already ravaged by toxic algae, invasive mussels and industrial pollution, North America's Great Lakes now confront another potential threat that few had even imagined until recently: untold millions of plastic litter bits, ...

Lampreys (sometimes also called lamprey eels) are a Predator family of Jawless fish, whose adults are characterized by a toothed, funnel-like sucking mouth. Translated from an admixture of Latin and Greek, lamprey means stone lickers (lambere: to lick, and petra: stone). While lampreys are well-known for those species which bore into the flesh of other fish to suck their blood, most species of lamprey are non-parasitic and never feed on other fish . In zoology, lampreys are sometimes not considered to be true fish because of their distinctive morphology and physiology.
